The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 31 hours and the median is 27.2 hours. Twenty-four of the families in the sample turned on the television for 16 hours or less for the week. The 7th percentile of the data is 16 hours. Step 2 of 5 : Approximately how many families are in the sample

Answers

Answer 1

Answer:

There are approximately 343 families in the sample.

Step-by-step explanation:

xth percentile:

A measure is said to be in the xth percentile if it is greater than x% of the measures.

Twenty-four of the families in the sample turned on the television for 16 hours or less for the week. The 7th percentile of the data is 16 hours.

This means that 7% of the sample size n is 24. So

[tex]0.07n = 24[/tex]

[tex]n = \frac{24}{0.07}[/tex]

[tex]n = 342.86[/tex]

Rounding up, there are approximately 343 families in the sample.

Answers

Answer:

37 centimeters

Step-by-step explanation:

First, since the triangles are similar, find out how much larger STR is than HIJ by finding an similar side and dividing the numbers. Since the only similar side that we know both numbers on it ST and HI, so we divide 10 by 4 to get the unit rate, which is 5/2. The missing side on STR is the bottom, so to get it, multiply 6, the bottom of the other triangle, by the unit rate, 5/2, to get the answer of 15. Then, perimeter is all of the sides added up, so 10+12+15=37 cm.

What is a right-angled triangle?

A triangle is said to be right-angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle.

Given:

An area of the right triangle = 24 square meters.

Height = 4 meters.

Then,

An area of the right triangle = 24 square meters.

1/2 x base x height = 24

1/2 x base x 4 = 24

Base = 12 meters.

Therefore, the base is 12 meters.

The volume of this cube is 1 ft. What is its surface area? A 6 ft. B 1 ft? C 26 ft? D 10 ft?​

Answers

Answer:

A

Step-by-step explanation:

The surface area of the cube is 6 ft².

What is a cube?

It is a polygon having six faces.

The volume of a cube is side³.

We have,

Volume = 1 ft³

The surface area of the cube = 6a²

Now,

Volume = 1 ft³

This means,

Side = 1 ft

a = 1 ft

So,

The surface area of the cube.

= 6a²

= 6 x 1²

= 6 ft²

Thus,

The surface area of the cube is 6 ft².
